GPS, ARPA, AIS, NAVTEX, VHF as modern aids-to-navigation equipments improve the safe navigation and help to reach a reduction in marine accidents by providing images, numeric values, texts, audio-based information for mates, However, we also noticed that it's complicate and difficult for a mate to acquire and analyze such information from these devices while he should devote himself to bridge watchkeeping especially in the urgent situation. Language is another way to get information and free the eyes and hands, so, to solve the problem above, we are trying to propose a new aids-to-navigation system, which can understand and merge multimedia marine safety information, analyze the situation and provide the necessary information in language. In this paper, we try to suggest a meaning interpretation model for supporting linguistic navigation safety information.

A recent advance in communication technologies accelerates the spread of food safety issues once presented by the news media. To respond to those safety issues and take steps in a timely manner, automatically detecting related information from the news data matters. This work presents an AI-based system that detects risk information within a food-related news article. Experts in food safety areas participated in labeling risk information from the food-related news articles; we acquired 43,527 articles in which food names and risk information are marked as labels. Based on the news document, our system automatically detects food names and risk information by analyzing similarities between words within a text by leveraging learned word embedding vectors. Our AI-based system shows higher detection accuracy scores over a non-AI rule-based system: achieving an absolute gain of +32.94% in F1 for the food name category and +41.53% for the risk information category.

This study was conducted to suggest potential future directions in the effective operations of food safety information on the internet. This study consisted of two sections. The first section was a survey that was performed by 186 dieticians in Daegu and Gyeongbuk area. The second section was the assessment of the quality of food safety information on the internet. 163 web sites that provided food safety information on three major searching engines using the search words 'food safety' and 'HACCP' were investigated. The trained panels evaluated the contents of the web sites using a 3-point scale assessment tool. The data collected data from the questionnaires were statistically analyzed using the SPSS package program (version 14.0). The results of this analysis were as follow. The primary purpose of internet usage by detitians was to search for information (87.2%). In addition, the detitians' satisfaction degree of food safety information on the internet was 3.17 out of 5 points. The operators of web sites that were evaluated by the researchers were business and industries (76.1%), public organizations (15.3%), and individuals (8.8%). The following four items, update of content, offer scientific basis or explanation of content, offer useful information and new informations, should be improved immediately. Among evaluation items, six items were shown to be significantly different according to the operators of web sites. The evaluation scores of web sites that were operated by public organizations were significantly higher than those of web sites operated by individuals or business and industries. In conclusion, regular and consistent qualitative evaluation of web sites is needed to improve the quality of information that is provided via the internet. In addition, web sites that provided information on food safety should be actively operated by public organizations.

This study presents a novel traffic information system which is capable of detecting unsafe traffic events leading to accident occurrence and providing warning information to drivers for safer driving. Unsafe traffic events are captured by a vehicle image processing-based detection system in real time. Surrogate safety measures (SSM) representing quantitative accident potentials were derived, and further utilized to develop a data processing algorithm and analysis techniques in the proposed system. This study also defined 'emergency warning area' and 'general warning area' for more effective provision of warning information. In addition, methodologies for determining thresholds to trigger warning information were presented. Technical issues and further studies to fully exploit the benefits of the proposed system were discussed. It is expected that the proposed system would be effective for better management of traffic flow to prevent traffic accidents on freeways.

The objective of this study is to review the safety and health information displayed on containers of humidifier disinfectants (HD). We summarized not only general characteristics related to the marketing and manufacturing of HD, such as the duration sold and the name of the company, but also the safety and health information, such as identification of disinfectants, recommended use volume, and precautions. All of this information was reviewed by HD brand. We collected safety and health information from 31 HD brands. We found that companies that sold and manufactured HD brands differ. Two companies were found to sell their HD without permission after 2011 when the health effects caused by HD were widely known. The name of the disinfectants were not identified on the container of HD. The recommended volumes were found not to be based on toxicological evidence and set without consideration of the level of susceptibility of users. Most companies displayed phrases such "this HD is safe for humans, even children" on the front of the container. No inhalation and skin toxicity precautions were provided. In conclusion, most HD did not properly display information related to safety and health to protect the health of HD users. There has been no official investigation to evaluate the risks posed by HD, such as the sales volume by HD, identification of chemical disinfectants, or their concentration, nor have there been actions to control the chemical quality of HD. In addition, government actions to punish the malicious practices of companies that manufactured and sold HD were found to inappropriate.

The repetitive occurrence of similar accident is one of the biggest feature in construction disasters. Similar accident cases provide direct information for finding risk of scheduled activities and planning safety countermeasure. Many systems are developed to retrieve and use past accident cases by researchers. However, these researches have some limitations for performing too much retrieval to obtain results considering construction site conditions or not reflecting characteristics of safety planning steps or both. To overcome these limitations, this study proposes accident case retrieval system that can search similar accident cases. It also helps safety planning using information retrieval and building information modeling. The retrieval system extracts BIM objects and composes a query set combining BIM objects with site information DB. With past accident cases DB compares a query set, it seeks the most similar case. And results are provided to safety managers. Based on results of this study, safety managers can reduce excessive query generation. Furthermore, they can be easy to recognize risk of a construction site by obtaining coordinations of objects where similar accidents occurred.

This paper presents a state-of-the-art review on the design, research and education aspects of fire safety engineering (FSE) with a particular concern on high-rise buildings. FSE finds its root after Great Fire of Rome in 64 AD, followed by Great London Fire in 1666. The development of modern FSE is continuously driven by industry revolution, insurance community and government regulations. Now FSE has become a unique engineering discipline and is moving towards performance-based design since 1990s. The performance-based fire safety design (PBFSD) involves identification of fire safety goals, design objectives, establishment of performance criteria, and selection of proper solutions for fire safety. The determination of fire scenarios and design fires have now become major contents for PBFSD. To experience a rapid and positive evolution in design and research consistent with other engineering disciplines, it is important for fire safety engineering as a profession to set up a special educational system to deliver the next-generation fire safety engineers. High-rise buildings have their unique fire safety issues such as rapid fire and smoke spread, extended evacuation time, longer fire duration, mixed occupancies, etc., bringing more difficulties in ensuring life safety and protection of property and environment. A list of recommendations is proposed to improve the fire safety of high-rise buildings. In addition, some source information for specific knowledge and information on FSE is provided in Appendix.
